AI Technical Summary

Benefits of technology

The present invention provides a method for modeling the steel volume with higher accuracy while keeping down the computing effort required. This is achieved by creating a method that takes into account the distribution of interstitial elements in the volume, as well as the enthalpy and the proportions of the different phases in the volume. The method also takes into account the relationship between the enthalpy and the temperature, which is dependent on the concentration of interstitial elements in the volume. This allows for the accurate prediction of the temperature in the volume without the need for additional provisions or divides. The method can be used in conjunction with existing methods for modeling the thermal conductivity and phase transition of the steel volume.

Problems solved by technology

This procedure leads however to very great computing outlay, but has practically no effect on the quality of the modeling.

Embodiment Construction

[0056]In accordance with FIG. 1 a computer 1 has the usual components 2 to 8. These are firstly a processor unit 2 and a mass storage device 3. The mass storage device 3 can for example be embodied as a hard disk. There are also interfaces 4 and 5. Interface 4 is an interface for connecting to the computer 1 a data medium 9 embodied as a removable medium. Depending on the embodiment of the interface 4 the data medium 9 can be embodied for example as a CD-ROM or as a USB memory stick. Interface 5 is an interface to a computer network 10, e.g. to the Internet or World Wide Web. The further components 6 to 8 of the computer 1 are an input device 6, an output device 7 and random access memory 8. The input device 6 can for example be a keyboard and a mouse. The output device 7 can be a terminal and a printer.

[0057]A computer program 11 is stored on the removable medium 9. After the removable medium 9 is connected to the interface 4 of the computer 1, the computer program 11 is read out T...

Abstract

A steel volume is modeled in a computer by means of a plurality of volume elements. The state of the steel volume at a given time comprises, for each volume element, characteristic quantities of an enthalpy existing at said time in the respective volume element and percentages, in which the steel is available in the respective volume element at the time in austenite, ferrite and cementite phases. For at least one volume element, the computer determines the time gradient of the characteristic quantities by resolving thermal conductivity and phase transition equations. One of the characteristic quantities is a locally invariable mean interstitial element concentration within the volume element in the austenite phase thereof.
